For single-phase jets, [1]} suggested that the Kolmogorov-length-scale \(\eta \)  is resolved if \(\Delta x / \eta \le 2.1\) , where \(\Delta x\)  represents the minimum computational cell size, and \(\eta \)  is estimated by \(\eta = Re^{-3/4} l\) , where \(l\)  is the length scale. Previous computational studies of temporal and spatial multiphase jets are presented in table REF , showing the current state-of-the-art in terms of Pope's criterion. It is evident that Pope's criterion is difficult to meet due to the high computational costs of the simulations. In their recent work, [2]}, [3]} performed simulations of a two-phase mixing layer between parallel gas and liquid streams to investigate the interfacial dynamics and the statistics of the multiphase turbulence, estimating the Kolmogorov length scale to be \(\eta \sim 0.945 \mu m\) , which leads to \(\Delta x / \eta \sim 3\) . Through their simulations, they estimated that \(\eta = 3- 4.5 \mu m\)  and also showed that their lower resolution mesh, i.e., \(\Delta x / \eta \sim 6\)  (see their figure 19d), was capable of predicting similar results in terms of turbulence dissipation.
